If ESP is not doing its job when it doesn’t have internal filters to set up for monitoring and catching spam.

Tiny bits of data have a journey of messages from router to router on the internet. Traveling from router to router the runner who carries the messages gets mixed with other types of email messages sent around the world every day.

ISP’s gateway filter checks the messages and enters the server or it gets rejected. It is the first step to filter our message which may encounter. Moreover, if it fails to guard this gate it may not be coming into the server of ISP’s.
